Answer:

$7.5

Step-by-step explanation:

if we set up the proportion \frac{10}{4} =\frac{x}{3}   with cost on top and water bottles on bottom, we can divide  10/4 too get 2.5, which we can then multiply by 3 to get our x value, 7.5.

Determine the standard form of the equation for the circle with center (h,k) = (-5 ½) and radius r =1
wariber [46]
Asuuing yo meant (h,k)=(-5,1/2)

equation is (x-h)^2+(y-k)^2=r^2
(h,k) is center and r=radious
given that (h,k)=(-5,1/2) and r=1
h=-5
k=1/2

(x-(-5))^2+(y- \frac{1}{2} )^2=1^2
(x+5)^2+(y- \frac{1}{2} )^2=1
if you wanted us to expand
x²+y^2+10x-y+25.25=1
